Our take
Dark underwater slot from Hacksaw Gaming with expanding siren wilds (up to 200× multipliers) and 10,000× peak.
Beast Below submerges players in a muted, haunting seascape where expanding siren wilds and lurking deep-sea horrors drive the action. Hacksaw Gaming has crafted an immersive atmosphere through restraint—the colour palette leans moody greys and blacks, punctuated by siren silhouettes and monster teeth. This aesthetic departure from bright, cheerful underwater slots gives the game psychological weight.
The siren wild is the payoff engine. Expanding siren symbols multiply payouts up to 200×, and landing multiple sirens during free spins compounds the escalation. A diver wild roams during bonus rounds, adding unpredictability to spin outcomes. The dual-bonus structure—two distinct free-spins modes—provides mechanical variety, though specifics remain locked until triggered.
With 14 paylines across a 5-reel, 4-row grid, Beast Below feels spacious yet manageable. The 96.29% RTP competes fairly for high-volatility releases. At 10,000× max, the ceiling sits mid-tier, reflecting the siren-multiplier focus over stacked symbol potential. The horror theme carries risk—players seeking lighthearted entertainment will recoil.
